A) If red hair were a recessive trait, it could be inherited in two ways: 1) from heterozygous parents who both carry the red hair allele (the chances of having a child with red hair would be 25%), or 2) from red haired parents who are both homozygous (100% chances of red haired offspring).
B) If red hair were a dominant trait, it could be inherited only if at least one of the parents had red hair. There's 3 variables: 1) If both parents were heterozygous, they would have a 75% chances of having red haired children; 2) if one parent were heterozygous and the other were homozygous dominant, all of their offspring would have red hair; and 3) all children would be red haired if both parent were homozygous, one dominant and the other recessive.
This exercise is an example of Mendelian inheritance which states that the genes inherited from parents are separated into gametes in equal frequency. Each parent "donate" an allele to their offspring; this allele could be physically expressed or not depending on it being dominant or recessive (this means: silent) and if the parents being homozygous or heterozygous. Heterozygous individuals have two different alleles (one dominant and one recessive), while homozygous can have either 2 dominant alleles or 2 recessive ones.
This sounds like a test cross. Because P is dominant, the purple flower could have a genotype of Pp or PP. If all of the offspring of the test cross are purple, then the purple flower has genotype PP. If half of the offspring of the test cross have purple and half have white, then the purple parental flower's genotype is Pp.

Yes, that's right. What's your question?
Explanation:
Answer: Water has unique properties that makes it an amazing substance. The cohesive forces are the intermolecular forces (hygrogen bonding and Van der Waals forces) which develops the tendency of that resists the liquids to separate.
As a result of this the water molecules forms droplets. These bonds lies in the molecules of the same substances.
Example rain droplets rather than a fine mist, water forms droplets.
